Hollywood actress Maggie Gyllenhaal is to star in a film about the invention of the vibrator.

In the upcoming film Hysteria, the Jewish actress will play the daughter of a doctor whose specialty is curing women of hysteria – in an unorthodox fashion.

The script is based on a true story, and follows a love affair between her character and one of her father’s assistants.

The Crazy Heart actress will also be returning to musical cinema in a biopic of the life of bluegrass musician Bill Monroe.

Her real-life husband Peter Sarsgaard will play the singer, while she will play his longtime love Bessie Lee Mauldin.
